Application tiled September 27, 19271. Serial No. 503,563.

To all whom it may concern.

Be it known that l, GEORGE Smear, a

citizen of the United States residing at Baltimore, in the State of Maryland, have invented certainl new and useful llmprovements in Mechanical Movements; and l do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the l Same.

washer and a clothes wringer, and a third shaft for casual connection to different mechanisms, the three shafts being driven s by a source of power through the medium the cover of the gearl casing being removedn of a member at is .arranged to slip if more than a predetermined power is being transmitted, so that fracture of the-parts of the driven mechanisms and serious in to showrthe operating parts.

lFig. 2 is, a section along the line 2-2 in Fig. 1, looking in the direction of the arrow.

'lnothe drawings f 5 is agear casing provided with a cover v6 secured thereto.

Bearings t and. 8 are provided in the casing 5 for the power shaft 9. A worm 16 is formed integrally with or 'mounted upon the shaft 3. and a roller bearing 11fsupports the thrust of said worm. The collar 12 secured to the shaft 9 prevents end play thereof, andv packing 13 compressed by the sleevexv 1t prevents egress of oil around said shaft.

'llhe worm 10 meshes with the worm wheel 15 which is clamped between the clamping discs 16 and 17 by. the spring 18. Fibre or other ksuitable washers 16 and 17a are interposed .between said discs and wheel.

19 thetgis'revolubly mounted in a bearing provided 'in the cover 6, and with a bearing portion onl which the wheel 15 is revo The disc 16 isfprovidedfwith a` bearing portion lubly mounted. The disc 16 and portions 19 and 20 lare preferably formed integrally and have a central cylindrical hole in which is slidably mounted the -shaft 21.

rllhe disc 17 is provided with a bearing portion 22 that is revolubly mounted in a bearing provided in the casing 5, and with a spur gear 23. The disc 17 portion 22 and gear 23 are preferably formed integrally andhave a central cylindrical hole in which is slidably mounted the shaft 21.

A spline 24C is secured in the shaft 21 and keyways slidably fitting' said spline are formed in the discs 16 and 17 and the parts formed integrally therewith.

rlhe spring 18 is compressed between the collar 25 secured to the lower end of the Ashaft 21 and the bearing portion 22 by means of the nut 26 threaded upon the upper end'ofsaid shaft and having its lower face bearing against the upper face ofthe portion 19. l

By this construction the discs 16 and 1'? positively drive .the shaft 21 and the gear 23, but said discs have only frictional driven connection with the gear 15. A squared portion 27 is provided upon the upper end of the shaft 21 for the reception of the socket of a dexiblef or other shaft for' driving various mechanisms. The end 27 is covered by the cap 28 when not in use. Ar boss 29 having a well for the reception of the portion 22, spring 18, collar 25 and shaft 21 is formed on the lower side of the casing 5. p l

yiFhree bosses 3() are formed upon the bottom of the casing 5 and in each of said bosses are formed bearings in which are 'revolubly mounted the ends of the shafts 31,

32 and 33. Bearings for the shafts 31 and 33 are also provided in the cover 6 and said shafts may be shielded by tubes 3a-3t it desired. 'lhe upper ends of the shafts 31 and 33 vmay-be used to drive any suitable mechanisms as., for instance, a clothes washer and clothes wringer, respectively.

The idler spur gear 35, fast on the shaft 32, is driven by the gear 23 and drives the gear 36 -fast on the Shaft 31.

The gear 23 drives the fast onthe shaft 33.

The casing 5 is to be filled with'grease or'oil to nearly the plane of the ton thereof at 3,8. lt is to be noted that parts requiring lubrication are placed below said lane in order to avoid leakage ofthe lubricant.

gear 37 which is i The operation of my improved mechanism is as follows and a cover for sai Power is to be applied to the shaft 9 to rotate it in the directionl of the arrow 39. This will rotate the wheel l5 and shaft 21 in the direction of the arrow 40 and the wheels 35, 36 and 37 in the directions of the arrows 41, 42 and 43, respectively. Should the rotation of either of the shafts 21, 31 or 33 meet with undue resistance, said shafts will stop and the shaft 9 will continue to rotate,

the wheel 15 slipping between the washers 16a and 172.

Thais -it will be seen that I provide a simple,cheap, ei'ective, and safe mechanism useful in drivingmany mechanisms in the household.

I olaim:- I

1. In a mechanical movement, the combination with a casing comprising a'bearyino'na'nd a cover for said ca sing comprising portion and a spring on said shaft bearing against said first named bearingportion and pressing said nut against said first named bearing portion, wherebysaid spring presses both said dises against said worm wheel.

2. In a mechanical movement, the combination with a casinar comprising a'hearing d casing comprisingI a Lawaai bearing, of a disc having 'a bearing portion revolubly mounted in the bearing in said casing,a second disc having a bearing porf' both said discs against said worm Wheel,`

.and a gear on one of said discs.

3. In a. mechanical movement, the com' bination with a pair of discs, each comprising a bearing portion for revolubly supporting said disc and a second bearing portion on one of said discs, 'of a gea-r Wheel revolubly mounted on said second Abearing portion. means for pressing said discs against said gear, and a gear driven by said discs.

4. In a mechanical movement. the combination with a pair of discs, each comprising a bearing portion for revolubly supjporting said disc and a second bearing porytion on one of said discs, of a gear 'wheel revolubly mounted on said second bea-ring portion. means for pressing said discs against said gear, a gear driven by 'said.\

discs and means for preventing /relative angular movement of said dlscs.

In testimony whereof, I aiiix my signature.
